hint.ahci.disabled=1 in /boot/loader.conf will accomplish the same
thing.
+* The installer errors out while trying to install a disklabel.
+ * Known issue. We blew the partition cleaning dd. Basically the
+ installer wants to install a disklabel64 but there is a standard
+ disklabel already installed. For safety reasons the disklabel
+ program refuses to blow away the old label.
+ * You can blow away the whole disk or the slice from the emergency
+ shell prompt (alt f3? alt f4?) and then start the installation over
+ again.
+ * dd if=/dev/zero of=/dev/<rawdisk> bs=32k count=4 **This will blow
+ away the whole disk**. You can try it on just the slice, aka
+ <rawdisk>s1 but it is fairly dangerous to do so be careful.
